While the benefits of exercise on physical health are well known; exercise has many other benefits.
In particular, resistance training, like weight lifting, is not just about being fit or muscular, it can also improve emotional and mental health.
A large study looked at resistance training and anxiety.
What was the study? (1,2)
This was review of 16 studies looking at resistance training like lifting weights (1,2)
Who was studied?
922 participants (1,2).
What was measured?
Validated anxiety outcome measures prior to, at mid-point, and after a period of resistance training (1,2).
What were the results? (1,2)
- Resistance training significantly reduced anxiety symptoms (Δ = 0.31, 95% CI 0.17–0.44; z = 4.43; p < 0.001) (1,2).
- Larger effects were found among healthy participants (Δ = 0.50, 95% CI 0.22–0.78) compared to participants with a physical or mental illness (Δ = 0.19, 95% CI 0.06–0.31, z = 2.16, p < 0.04). (1,2).
- Effect sizes did not vary much according to sex, program or session length, frequency or intensity. (1,2).
What are some other mental health benefits of exercise?
- A review of 15 years of research shows that exercise can improve brain function (4)
- A study of 33,000 people over 11 years demonstrated that exercise may prevent depression with 1-2 hours PER WEEK of exercise (5).
- May help reduce alcohol use disorder (6)
- Reduce chronic fatigue (7)
- Improve sleep (8)
How much should I exercise?
The recommended exercise duration according to The National Institute of Health’s “Physical activity guidelines for Americans” (9, 10):
- For moderate intensity activity, 20 to 42 minutes a day (150minutes to 300 minutes per week).
- For vigorous intensity activity, 10 to 21 minutes a day (75 to 150 minutes a week).
What are some examples of moderate and vigorous intensity activities? (9, 10)
- Some examples of moderate intensity activities include walking, water aerobics, slow bike rides, etc.
- Some examples of vigorous intensity activities include jogging/running, Bicycling 10 miles per hour or faster, lifting weights/resistance band training.
What are some precautions?
- It may be best to check with your healthcare provider to make sure it’s safe for you’re to start an exercise program.
- It may be wise to stop exercise and seek professional help if you notice:
- Increased depression, disordered eating, and other mental health concerns.

- Exercise may not help without proper nutrition.
- It may be wise to learn about proper nutrition and proper exercise technique, and exercise/nutrition plans, before starting to exercise.
- It may be helpful to gradually start exercising to give yourself time to adjust to an active lifestyle.
- It might take weeks months or longer for some people to get used to and enjoy the minimum activity guidelines.
- Occasional periods without exercise may be important to prevent injury.
- Figuring out what works best for you may give you lasting benefits.
